Where does the water come from? The City and County of Broomfield’s water supply originates on the western slope of Colorado and is transported through the Colorado-Big Thompson (CBT)/ Windy Gap system under the management of the Northern Colorado Water Conservancy District, and is stored on the eastern slope in Carter Lake in Larimer County.
The Windy Gap Project consists of a diversion dam, a pumping facility, and a pipeline to Lake Granby. The CBT system consists of a total of ten reservoirs, thirteen dams, six power plants, three pumping plants, and associated canals and waterways. The Alva B. Adams tunnel is a means of conveying this collected water 13.1 miles through the Continental Divide to the eastern slope. After leaving the tunnel, the water falls through six power plants and eventually into Carter Lake. A 32-mile water conveyance pipeline from Carter Lake to the Matthew D. Glasser Reservoir supplies the water used by the City’s treatment facility.
The City and County of Broomfield also purchases potable drinking water from the Denver Water Board. The staff of the Water Supply Division consists of two full-time positions and two seasonal positions. For additional questions, please call 303-464-5600 |
